Which external codes are not used to report intent for drug-related issues?

The correct selection is based on the context of how external codes are categorized in ICD-10-CM. The range T36-T65 refers to codes that specifically pertain to poisonings, adverse effects, and drug reactions involving various substances. These codes are generally utilized to report intent for drug-related issues, such as misuse, accidental ingestion, or adverse effects stemming from drugs.

In contrast, the other ranges provided do not serve this purpose. The Z00-Z99 codes primarily represent various factors influencing health status and encounters for special examinations; they do not directly relate to drug-related intent. The A00-A99 range contains codes for infectious and parasitic diseases, which are unrelated to intent in drug-related contexts. Lastly, the M00-M99 codes focus on musculoskeletal diseases and do not encompass drug-related issues.

Thus, T36-T65 is the only range specifically employed for reporting drug-related intent, making it the correct option for identifying external codes not used to convey this information.
